Studies show that the size of magnetic nanoparticles has an important impact on their properties. So, the possibility of an optimal size for their use in medical applications has been reported. Therefore, in this study, cobalt ferrite nanoparticles were prepared using co-precipitation method at 80°C; then the powder was annealed in a furnace at 150, 200, 300, 400, 500 and 600°C to obtain nano...
